Preheat your oven to 425°F. This step is crucial for achieving that bubbly, golden cheese on top. Get your casserole dish ready by spraying it with nonstick spray to prevent sticking.
In a medium-sized bowl, combine the Taco Seasoning with the shredded chicken and mix well. The seasoning will infuse the chicken with a fantastic flavor profile, so ensure it’s evenly coated and set aside.
In a food processor or high-powered blender, combine the spinach, cilantro, and salsa. Pulse until fully chopped and mixed together, creating a vibrant green mixture that will add freshness to the lasagna.
Layer six tortillas into the bottom of your prepared casserole dish, overlapping them slightly. This will create a solid base for your layers.
Cover the tortillas with one cup of shredded Mexican Blend Cheese, followed by half of the black beans, half of the corn, and half of the seasoned chicken. Add a cup of the spinach mixture over this, ensuring even distribution.
Repeat the layering process by starting with more tortillas, then adding the remaining black beans, corn, and chicken. Top with the rest of the spinach mixture and finish off with the remaining cheese.
Cover the dish tightly with foil and bake for 30 minutes. During this time, the flavors meld together and the cheese begins to melt and bubble.
After 30 minutes, remove the foil and continue baking for an additional 10 to 15 minutes or until the top is nicely browned and bubbly. This step is crucial for that perfect cheesy topping.
Once done, remove the lasagna from the oven and let it sit for a few minutes. Serve warm, topped with your choice of jalapeños, plain Greek yogurt (or low-fat sour cream), and fresh cilantro for a delightful finish.
